THere are a lot of places open in the winter months with at least electric hook ups. Never been to leavenworth in the winter. But a number of the ski area;s have hookups. Including WHistler and some of the ones in the Okanagaon valley in BC. Stevens and Chrystal locally have electric hookups. I;ve also been to MIssion, Scwietzer, Timberline, mt hood in the RV to ski also.
All the above are reasonably easy to do, just need to give yourself some time if the road is a bit tough. Correct tires, not street tires, then chains are a must a lot of times to.
As someone noted, yeah, the first time is interesting, after that, like all things, you get used to it, and it gets easier per say. Or at least you learn what to expect in certain conditions.
Timberline was fun coming down with 40-60 mph winds, snowing, compact snow on the road. 10$ for 6 miles. Stopped in the middle, one person in front a couple of vehicles, got out, was on there kiester before they could take a breath or heart beat!
Then on some grades, your tires are just warm enough to melt the ice/snow, putting a bit or water under your tires, and down the hill you go! Locally King 5 an NBC affiliate has or had some winter driving videos. Fun watching the bumper cars in some of Seattles 5-10% grades! You do not see folks trying to drive on the 15-26% grades, THose like queen anne ave, 18% have closed signs top and bottom. Not to mention bus route changes......
